Abstract: Le véhicule décrit comprend un châssis (25) porté par des paires respectives de roues avant et arrière (30, 31, 32, 33), ainsi que deux unités à piston et à cylindre (23-24, 35-36, 37-38, 34-39) qui sont associées à chaque roue et qui sont connectées entre la roue (30) et le châssis (25), de sorte que le piston se déplace dans les cylindres en réponse à un mouvement relatif entre la roue et le châssis. Un circuit hydraulique individuel (40, 41, 42, 43) connecte une unité à piston et à cylindre (23) de chaque roue (30) à une unité correspondante (34) longitudinalement espacée de l'unité à piston et à cylindre sur le même côté du véhicule, ainsi que l'autre unité à piston et à cylindre (24) de chaque roue à une unité correspondante (35) sur le côté transversalement opposé du véhicule. Grâce à un tel agencement, la pression hydraulique dans n'importe laquelle des deux unités à piston et à cylindre interconnectées par un circuit hydraulique individuel est égale et tout mouvement relatif entre n'importe quelle roue et le châssis du véhicule produit un mouvement relatif opposé entre le châssis du véhicule et la roue dans le circuit hydraulique, ce qui maintient l'adhérence au sol de chaque roue et, partant, sa force de traction.

Abstract: Amplificateur de puissance entièrement différentiel, comprenant un étage (A1) d'entrée de gain élevé et un étage (A2) de classe AB réalisés en technologie MOS complémentaire. Chacun des deux étages (A1, A2) est doté d'un circuit de réaction (CMF1, CMF2) de mode commun destiné à établir le point de travail, optimisant ainsi la gamme dynamique globale de l'amplificateur. De plus, on a prévu un circuit (BWD) de réduction de dissipation de puissance, destiné à limiter la puissance dissipée pendant l'état de repos de l'amplificateur de puissance. Notamment, la topologie de l'amplificateur est entièrement symétrique. Ainsi, on obtient un signal de sortie à gamme large sous une charge ohmique faible, une distorsion harmonique très faible, ainsi qu'une faible consommation de puissance.

Abstract: The invention relates to a safety device on a motor vehicle, in which a support element is moved from a position of rest into an active position in a direction of acceleration occurring for a vehicle occupant (2) in the event of an accident. This adjustment takes place automatically as a function of the vehicle state before the start of travel. According to the invention, the support element (10) is adjustably arranged on at least one vehicle seat (7), on its side directed towards the outside of the vehicle or towards the associated vehicle door, in such a way that in its active position said element covers from the side the lap area assumed by a seated person. In this way, it is ensured that in the event of a lateral impact a person (2) is not thrown from the vehicle seat (7) in the direction of adjacent vehicle parts which are forced into the passenger cell in the event of a lateral impact, as a result of which the risk of injury and, if injuries occur, the severity of injuries, is/are reduced. <IMAGE>

Abstract: The invention relates to neural networks intended especially for classification of objects represented by vectors X. 
<??>If the vectors X comprise numerous parameters and if the objects must be classified into a large number N of classes, networks with a very large number of interconnections are arrived at, which become difficult to produce physically, which are slow in operation and have a long learning time. 
<??>The invention proposes a system for neural classification which has the feature of being constituted from P neural networks each individually carrying out the classification of objects between only two classes or, in any event, only a small number of classes. These networks provide probabilities Pij of belonging to a class Ci among two classes Ci and Cj. The outputs of these networks are connected to a signal processing module (3) which, via simple functions (employing linear combinations of the outputs and of the non-linear normalisation functions) establishes, at N outputs, results Pi(X) of classification among the N classes. Learning is done on classifications by pairs of classes, but recognition after learning supplies classifications among N.
